19.13 Hold the spring mount down, and lift the stepper motor and mounting bracket off the spring
mount and module and stator sub-assembly.
19.14 Lightly press the spring mount and old pinned rotor assembly together, so that the four springs
are retained between them, and do the following:
19.14.1 Lift them off the module and stator sub-assembly.
19.14.2 Turn them over and place them on a flat surface, so that the pinned rotor assembly is
on top.
Note: It will be easier to disassemble and re-assemble the components if the pinned
rotor assembly is on top.
